and all debris and airlocks have been removed before turning your water heater on. By
bypassing this step you risk irreversible damage to your water heater that will not be covered

Operation
Once the system has been plumbed and wired in accordance with this manual it is time to
switch the mains supply on.
When power is supplied to the unit the indicator light will illuminate to show that the system
is ready and beginning to heat the water.
The dial on the outside of the case can be used to control the temperature that the internal
water store is heated to, turning this higher will increase the store temperature, turning it
lower will decrease it. We recommend adjusting the thermostat over a few days until the
desired temperature is achieved. Remember to run the heater only at the temperature
required to avoid wasting energy.
In the event of overheating there is a safety cut out stat built into the unit. This has a
resettable switch that can be pressed to reset and can be found on the immersion heater on
the inside of the unit. We recommend that you have a proper engineer service the unit and
this is not attempted by the user.
The immersion heater is located below the grey plate on the underneath of the unit. If the
unit has been installed so this plate is inaccessible please disconnect the unit from the mains,
isolate the water supply, drain-down and remove the unit from the wall for maintenance.
before attempting to maintain the unit please ensure you have isolated the
electricity supply.

"
BSP fittings and these connections are clearly
marked on the unit. It is important that these two connections are not swapped over.
The connection from the heater to the system pipework should be made using flexible
stainless steel hoses, this facilitates the operation of the unit and also makes future
maintenance easier.
The pipework used should be capable of with standing 7.5 bar of working pressure and
temperature in access of 80

C.
the included safety release valve must always be fitted without exception and should
have no obstructions whatsoever between the valve and the heater itself. always make
sure that the discharge vents to a safe and visible location so as to provide a visible
indicator that the system is not performing as expected.
Once the unit has been completely plumbed in accordance with this manual please ensure
the system is flushed through completely by opening the outlets for a minimum of 10
seconds, all air and debris should be purged from the system before operation.
Under certain circumstances it may be necessary for additional safety components
to be fitted to the system installation, please see
fig. 3

installation configuration and any potential equipment that may or may not be required
to complete the installation.

requirements and local regulations at the time and in accordance with the latest IEE
regulations.
